Application filed November 16, 1903. Serial No. 181,321.

ATo allwhofm, 'it/may concern:

Be it'known that I, WILLIAM L. MoRR'Is, a citizen of the United States, resident of Ba-I .tavia, county of Kane, andY State of Illinois,

have invented a new and useful Improve# ment in Lubricating-Mechanisms, of which the following is a specification, the principle of the inventionbeing herein explained and the best mode in which -Ir have Vcontemplated applying that principle, so as to distinguish it from other inventions.

My invention relatesfo lubricating-devices and particularly to that class of such devices in'wliich a pump is utilized for forc` ing the lubricant to the desired points.

The object of my said invention is to provide means for the above-named purpose "whichshall' be economical of operation and construction.

Said" invention consists of means hereinafter fully described and particularlyset forth in the claims.

The annexed drawings and the following description set `forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in whlch the principle of the inventionmay be used.

' In said annexed drawings-Figure l represents a vertical axial section of a device j Yy.fembodying my invention, showing the interior mechanism principally in elevation. Fig. 2 represents a vertical axial section taken upon -a plane at right angles to that of the section shown in Fig. 1. Fig. 3 represents plan view of such device with the cover removed, and Fig. 4 a horizontal detail section taken upon thepla-ne indicated by line IVIV, Fig. 2.

A bowl or casing A constitutes the reservoir for containing the lubricant, which will usually be a more or less freely flowing oil. Such oil reservoir or tank has its upper portion threaded. as shown, and upon such threaded portion is screwed or otherwise detachably secured a cover or plate B p1 o7' vided at its top with an opening and a removable cap b. The cover B has secured to or formed integral therewith, preferablythe latter, a depending structure forming chambers, ducts, guides, etc.. which will be hereinafter fully described. Means for the exterior attachment and supportof the lubricator are, in the form of the device illustrated inthe drawings, provided by an arm integral with such cover member B and designed to be secured to awall'or other firm' support, as isrnost convenient. The lower portion of the structure depending from member B 'forms two chambers b b', eacli' of which is provided. with an .-inlet valve b24 and valve opening b4, and an outletV valve b3, and opening b5, as shown in Fig. 2.

These valvesl are arranged in the manner of ordinary pump valves whereby fluid may be pumped from the reservoir or tank A, into the chambers b l1. and out through valve openings b5 as will be readily'understood. Into each such chamber extends a vertical plunger, be bs, the upper endof which is secured to a' yoke or cross-head B. These plungers are packed by means of glands bl 6"' and suitable packing 1n the gland chambers, as will be understood. Having its extremities bearing upon the two glands respectively, is a spring-bar, or plate, Clield in place by means of an adjusting screw C' whose lower end isthreaded into a cross-bar 58 that forms an integral part ofthev cover structure. The ends vof such" spring-bar are bifurcated, as shown in Fig. 2, so as to per-4 mit the same to bear upon the'middle of the glands and so hold them firmly in'place. It will be seen that by nieansgof screw C', the glands maybe held in place with varywing degrees of intensity, as 'a result of the varying force which may be imparted by such spring bar. The interior open space b9 formed in the cross-head B isfoimed'with a flat bearing surface 51 transversely located, as shown, relatively to the heads direction of travel. The Aupper part of the head is formed with a tubular extension bu, which slides ina guide 1212 forming an integral part of the structure as shown.. Into this extensionis threaded a tubular adjusting member D, whose lower endis closed and formed with a' flat bearing surface cl dispose opposite surface b1 and extending similarly in a transverse direction. These surfaces 51 and ai are located centrally of the head as shown. Upon the lower portion of the interior of member D is secured the lower end of a spring-rod cl', upon which is secured a pin cl2, which passes throughan aperture d3 formed in the member D, the outer end of such pin projecting a` short distance beyondV the outside of said member, and being adapted to engage any one of a series of vertical grooves 613 formed upon the interior of the extension 611, as shown in Figs. 1 and 4. By these means, the member D .may be locked in various positions. The depending structure is furthermore formed with a horizontal lbearing 6'14 in which is journaled an arbor ',E whose inner end is provided. with an eccentric', or crankwrist-pin, e which extends vinto space 69 between surfaces 610 and'` d. Upon lthe pin is journaled an anti-friction roller e', suitably secured against displacel'mentt The adjusting member D is made of a' length to permit it to be lowered sufficientl `to cause surface d to bear upon roller e while the latter is in engagement with surface 610 as shown in Fig. 1. It will thus be seen that the length of stroke of the cross-v head, and hence of the plungers, may be varied between lzero as a minimum' and the throw of the pin e as a maximum.4 'To the outer end of arbor E, thus seen to constitute g a pump-operating shaft, is secured a wormwheel F which is'rotated by means of a worm F secured upon the inner end of a shaft F2 journaled in a bearing 615 formed in the cover',B. This shaftprojects externally of 4 thecover through `saidbearing, and upon its outer end. is secured a driving sheave,- f. Suitable packing is provided forfmaking the bearing 6L5 dust-proof, as shown in Fig. 1.

Leadin from each of the valve o enings 65 upwar ly is a discharge duct 61G ranching horizontally at its u per portion and 4intersecting the outer surace of the cover,

Fig. 2, at which point a tube may be atbore 619 is a valve stemg, the outer end of which is providedwith a thumb-piece' gf by means of which the stem may be turned. The-inner end of said stem is provided with a double valve g2 and' with two piston portions g3 and g4. at eachv sidel of the latter. These piston portions are adapted to .enter and close the bore 6" and duct 61, respectivelyl and are of a length such 'that both said duct and bore are not lef't'open'simul-` taneously but are alwaysfop'ened and closed consecutively. Stem pass around it and throu h the'passage-way 62o when'the valve is o seat,- 618. It will thus be seen that each chamber 6 lmay be placed 4in communication with the interior or the exterior of the tank throughthe meis formed with a {rel duced portion g5 wiereby lubricant mayA dium of valve g2. Immediately above the valve-stem g is the cap '6, by the removal of which the thumb-pieces g are rendered conveniently accessible for purposes of adjustment. A

In operating the above-described mechanism, valves g2 are'caused to close the ,valve openings 621 and so open ducts 61G to communication with the bowl A through passage-ways 620, such tank. or reservoir being Supplied with the requisite amount of 'lubricant. The mechanism now being starter;

or being already in operation, lubricant 1s pumped up through ducts 61G and discharged -through ways 620.] The cap 6 havingbeen removed, the quantity oflubricant being pumped may be observed. If it be desired to change such amount, the adjusting-member D is turned so as to alter the throw of the lungers so as'to obtainl the amount of disc arge required. When such amount ,has been obtained, valves g2 are caused to open openings,l 621 and close openings 61 thereby diverting the discharge into the branches of ducts 610. The cover is now replaced and 4the discharge continued as required.

Aside from the novel features involved in the construction and discharge connections l of the pump of vmy improved lubricator, I desire to call particular attention to the fact that the 'oil receptacle A is removably secured to the fixed pump-supporting member B thereby permitting ready access at all times to the pump mechanism for purposes' of inspection or repair. Obviously it is 1mmaterialV which of these two members, the pump-supporting member or the oil-containing member, be thus fixed and which detachable. In some cases, indeed, itmay be more convenient to have the latter externally supported and the 'former removable. By applying the term f cover to member B, it -should be finally explained, I do not mean necessarily tdimply that such member effects, in itself, ya' complete closure of the reservoir, or lubricantcontaining casing A; In its general-aspectsmember B is the support lfor the various operative parts of the device, and the termin question is intended to connote this' function','a's"w'ell as vitsfunction as a. cover fornthe'reservoir which it serves in conjunction with the cap 6.

Other modes of applying the principle of my invention maybe employed instead of the one explained, change being made as regards the mechanism herein disclosed provided the-means stated by anyone of the following claims or-the equivalent of such statedfmeans be employed.
